The increasing public concern of potential health problems, due to improper waste
disposal practices as well as the introduction of landfill taxes, have induced the practice of incineration. Presently, all UK incinerators have to meet very strict emission levels. In this way, the generated fly ash residues have to be managed very carefully as they are enriched with toxic organic micropollutants and heavy metals.
The aim of the present work is to describe a novel thermal technology, known as the ash
detoxification process, that has shown success not only in the destruction of its toxic organic components, but also in the fixation of its heavy metal content to form an unleachable material.
